...this plane for being the NASTIEST, DIRTIEST aircraft currently in flying condition (if you can call it that).  I would be SCARED to board this dirty bird

[Isak922]

EEGAD!

Anyone want to do some volunteer plane cleaning?  ;D

[eno]

I think that dog has just shown his opinion of it ........ and attempted a token jet wash  ::)

[Papa9571]

I dont think that aircraft has been in the air for quite a while. It kinda looks like it has been abandoned.

[Tweek]

I prefer the look of a used aircraft, rather than one that's shiny and fresh out the paint shop, but that just takes the biscuit.

[ATI_7500]

Acoording to the other pics of this one, it hasn't been flying for quite a while.

And I doubt they'd let it take of this dirty, since the increase in fuel consumption will be way more expensive than a quick wash.

[MWISimmer]

It's not as dirty as some of Air France's aircraft... even some AF textures for FS have dirt as standard..

[Canuck.]

There used to be a floatplane (a Seawind I think) that parked outside of my Dad's house when he lived on a lake, that had parts held on with duct tape, and it even sank a couple of times, but it's still out there flying.

[JA 37 Viggen]

Well all the DSB GR.4s look like that!

And the Ukrainians are too poor to get a decent paint job.

And as for the F-4F.... most likley the last to the the F-4ICE upgrade.

[Craig.]

Air france and US air are both notorious for having really dirty planes.

[bok269]

I doubt that things still flying.

[Boss_BlueAngels]

Yeah, that's pretty bad.  But I have to say there is a significant difference between airplanes that are dirty from extensive use and those that are dirty from a lack of use.  

[ATI_7500]

That F-4F doesn't look that dirty to me...
